IMPROVEMENT IN S TENCILPLATEE 4113119 Schedulexefened to in these`Letters Patent and making part-of the same.

To all whom tt may conce/rn.-

Be it known that we, JEROME L. TARBO'X and H.'

.L TARBOX, of New York, in the county of New York,

and State of New York, have invented a new and useful Improvement inStencil-Plates; and we do hereby declare that the following is a full,clear, and exact de scription thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part 0f this specification.

This .invention relates to improvements in -stencilplates, designed toprovide a simple and convenient arrangement whereby the stencil-lettersmaybe readily connected together, for forming words, and be as readilydisconnected, for changing their combination, without the. employment offrames for holding them when 4set up, ass now commonly practised.

Figure l represents a plan View of our improved arrangement, and AFigure 2 represents a perspective view of the same. Similar letters ofreference indicate corresponding parts. 4 f We provide each plate,A,Awherein a letter is formed, with the bent-springs A', having two .ormore sets of notches, B.

The said springs are secured to the top of theplates, near the ends, andprojecting over one edge thereof.

We also provide thesaid plates with the hoods O, on the opposite edgesof'the plates Afhaving openings in their outer ends, and catches, D,capable of engaging thenotches in the springs.

One edge, E, of the plates is elevated, while the other, F,projectssuiciently to lap under the edge E when they are connectedtogether.

When th plates are arranged together, to form a word or combination ot"letters, vthey are placed side by side, and the springs A of one platepressed into the hoods O, until the notches in the said springs engagethe catches D, whereby they are held firmly together, and the edgeslapped, so that the ink cannot pass between the plates.

If it be desired to arrange the letters in curves, two or more setsoinotches, B, may be made in the springs, and the innermost set engagedwith the catches D at one end, and the outermost at the other. Y

In order to connect them, so as to form two or more rows, we provide theloops or eyes G, at each end of the plates, and connect -the rowstogether by a wire passing through the said eyes. Instead, however, ofthe eyes, spring-catches, or other similar'devices may be employed.

To disengage the plates for changing the combinations of letters,the'sprngs A', the ends of which project vslightly beyond the hoods, arepressed down sutliciently to disengage the notches therein from thecatches D. v

. Other arrangements of the springs A', and their catches, may beemployed with good results, but we prefer the plan which we havedescribed.

l'. Stencil-letters, arranged to be readily connected vor disconnected,by springs on one section taking into notches, or behind projections onthe other sections, substantially as specified.

2. lThe arrangement ofthe springs A', hoods C, and catches D,substantially as specified.

' 3. The plates A, arranged for lapping the thereof, substantially asspecified.

4. Stencil-plates, arranged to be united to form rowg by means of theloo s G, and rods or equivalent devices, substantially 'as specified.

The above specification of our invention signed by us, this day of 1869.
